I have introduced the impact exsolution hypothesis to link the Chicxulub collision and the state change in Deccan volcanism. This research explains how planetary scale collisions may trigger volcanism: when large objects such as asteroids or comets hit planets, they generate seismic waves that cause exsolution in magma, which initiates eruptions. Since co-occurrences of impactor collisions and volcanism have been linked with mass extinctions, this may help improve our understanding of the events surrounding the Cretaceous-Paleogene boundary. Further, impacts may have triggered past volcanic eruptions on Earth and other planets, and may play a role in triggering future volcanic eruptions.
